Could you build this?
No This is a video generation model. Building a comparable one requires training or post-training large models on massive GPU infrastructure and proprietary video data, which vibe coding cannot provide.
What it would actually take: Serving the model needs large GPU clusters, inference optimization such as distillation and quantization, and a training pipeline on a large licensed video corpus. A competitive version requires ML research teams and months of compute, far beyond a solo build.
